UNITED STATES PATENT OFFICE GEORGE E, EEAZIER, E GRAFTON, AND LBERTE. HERROLD, or PITTSBURGH,

PENNSYLVANIA DERAILER Application filed November This invention relates to derailers for railway vehicles more particularly to derailers of the type which are permanently fixed to a rail and adapted to be moved into and out of derailing position in accordance with service requirements.

It is among the objects of this invention to provide a derailer of simple, compact and durable mechanical construction which shall 1 embody a minimum number of operating parts and which is especially designed to be eliicient in its function of derailing vehicles passing thereover.

Another object of the invention is to pro- 1 vide a derailing device which shall be designed to support the weight of a vehicle on the rail with whichit cooperates and to receive the thrust on its supporting base in a manner to prevent relative displacement of the derailing member when the latter is sub jected to'the forces acting upon it.

Another object of theinvention is to provide a derailing device which shall be rendered operative or inoperative by the operation of a lever and which when inoperative is placed in position to prevent interference with the vehicles passing over the rail.

These and otherobjects will become more I apparent from a consideration of the 'accompanying drawings in which like reference characters designatelike parts and in which Fig. 1 is a side elevational view of a derailer embodying the principles of this invention and illustrating the derailing member in its operative or raised position; Fig. 2 is a similar view showing the derailing member in its inoperative or downposition; Fig. 3 a top plan view of the derailer shown in Figs. 1 and 2; Fig. 4 a sectional elevational view taken along'the line IV IV, Fig. 3 and Fig. i 5 a sectional elevational view taken alongthe line VV, Fig. 4. I

Referring to the several figures "of the drawings the structure therein illustrated comprises a derailer embodying a base gen} erally designated at 1 having flanges 2 3) provided with openings?) for receiving spikes or bolts by means of which the base is firmly secured to the rail supporting ties. The portion of thebase adjaeent the rail, is

having an opening 9 therein for receiving the l on the rail.

the slotted engagement with the lag 19 and 1, 1927. Serial No. 230,259.

formed of a relatively heavy section of metal 4; (Figs. 2 and 5) having inclined seating portions 5, 6,7, and 8 in spaced apart relation as shown in Fig. {L The portion 4is further I provided with an upwardly projecting lug 1O pivot bolt of a link 11 which connects a derails ing member 12 with the base 1. a

The derailing device consists of a track portion 13 which is adapted to seat on the rail 14 with whichit cooperates to derail a vehicle passing thereover. The track 13 is provided 1 with anincline 15 which connects the upper level or plane of the derailing member with j the top of the rail 14 and functions to lift the tread of a wheel passing over the rail. Adjacent the lifting track 13 is a depressed web portion 16 to provide clearance for the flange of the wheel.v A flange member 17 is formed, integrally with the web 16 and track portion 13 and is of such'angularity as to constitute a divergent path for the wheel to derail the vehicle. 1 a

The derailing member is provided with a lug which is pivotally connected to the link 11 to maintain proper spaced relation of the .derailing member with its supporting base location of the engaging seating surfaces, the

derail 12 is adapted to resist the thrust imposed upon it by the forceof a wheel passing overthe :derailing member 12 without stressing any weak portions of the derailer and i without the possibility of displacing the derailing member from its operative position I For this purpose a depending lug 19 is provided on one side of the derailing member which cooperates with a slotted portion 20 of the base, the bottom of which constitutes the seat 8 illustrated in Fig. 4. The purpose of slot 20 of the derailing member and base respectively, is to take up end or side thrust which may be imposed on the derailer, par ticularly when a vehicle passes over the rail in the reverse direction, that is, in the direction opposite to that for which the derailcr is designed to operate.

The derailing member 12 is provided with a portion 21 terminating in a transverse rib 22 from which a pair of guide arms 23 are projected and which is further provided with downwardly depending lugs 24;. The guide arms 23 pass underneath an enclosed portion 25 of base 1 and project through slotted openings formed in. the rear wall 26 of the enclosed member, these openings constituting guides for properly directing the movement of the derailing member 12.

The lugs 24: are provided with openings for receiving pivot bolts 27 by means of which a yoke or lever portion 28 is pivot-ally connected, this lever being the operating lever which may be either mechanically or manually operated in any suitable manner toraise and lower the derailing member on its base.

As previously explainechthe base 1 is secured on the cross ties of a rail with the end portion 4c of the base adjacent the web of the rail 14. To further provide against displacement of thebase it may be desired to employ a pair of straps 30 having flanged ends 31 for engaging the base of the rail and a flanged end 32 thatengages the rear of the base as shown in Figs. 1 and 2. These straps are provided with perforations corresponding to the opening 3 in the flange 2 of the base and are secured in their proper position on the railway ties at the same time when the base is fastened. in the manner explained above.

In the operation oi the device the derailing portion 12 isnormally in its operative position which is that shown in Fig. 1, such devices being usually located ona portion of. the rail beyond which it'is dangerous for vehicles to pass. This is the portion at which the base is firmly secured, but since itis at times necessary to permit the passage'of vehicles beyond the portion of the rail onwhich the derailer is located, the derailing member 12 may be displaced or moved to its inoperative position by means of lever 28 which is actuated to withdraw the derailing member 12 from the rail and in so doing the cooperating engaging seats oi? the derailer and base members separate without any interference, the seating portions being particularly shaped for this purpose. In its disengaging movement the derailing member 12 slides from the topoi the rail and moves rearwardly, the guide arms 23 functioning to maintain the proper position of the member 12, and

link 11 connecting the member 12 and base 1 assuresa fixed spaced relation of these parts for any position of the member 12 on its supporting base.

l/Vhen the derailing member 12 is in its inoperative or lowered position as shown in Fig. 2, it is entirely out of the way or vehicles passing over the rail 14 and this is made possible, within the limits of the space permitted by the height of the rail, by the pivotal link connection and the guide arms 23.

It is evident from the above description of this invention that a derailing device made in accordance therewith, is adapted to be located on the rail with which it cooperates during its derailing action and to be further supported on its base in such a manner as to guard against displacement when the force of derailing is exerted thereon. It is further evident that the derailer hereinbetore illustrated and described comprises a simple de sign which is practical, durable and relatively inexpensive to manufacture, and that the actuating mechanism is designed to be etiicient in its movement of the derailer to its operative and inoperative positions.

Although one of theembodiments of this invention has been herein illustrated and described, it will be obvious to those skilled in the art that various modifications may be made in the details of construction and in the design and arrangement of the several coopersting parts without departing from the prin ciples herein set forth.
